Science Impacts of 2011 Re‐Plan

• Science payload and supporting capabilities remain intact; no significant augmentations or descopes.  Payload Flight Models will all be received at JPL b th d f l d 2009JPL by the end of calendar 2009.

• Additional time to address actuator technical issues (including cold‐temperature performance) and the build & test of the Sample Acquisition, P i d H dli S t ill h iti i t iProcessing, and Handling System will have a positive impact on science return.

• Project may baseline 5 day/wk operations after Sol 180 to cut Phase E t i t i i t b t h j tifi ti f MERcosts; impacts mission return but has some justification from MER 

experience.

• Four candidate landing sites from 2008 remain in the baseline and so far tibl ith th 2012 i l diti P j t ill k ith thare compatible with the 2012 arrival conditions.  Project will work with the 

Landing Site Steering Committee in FY10 to consider whether a single additional site is warranted by any late‐breaking discoveries (e.g., MRO, MEX, ODY, methane, carbonates, and chloride deposits)., , , , p )

Four Candidate Landing Sites

Eberswalde Crater (24°S, 327°E, ‐1.5 km) contains a clay‐bearing delta formed when an ancient river deposited sediment, possibly into a lake.  

Gale Crater (4.5°S, 137°E, ‐4.5 km) contains a 5‐km sequence of layers that vary from clay‐rich materials near the bottom to sulfates at higher elevation.

Mawrth Vallis (24°N, 341°E, ‐2.2 km) exposes layers within Mars’ surface with differing mineralogy, including at least two kinds of clays. 

Holden Crater (26°S, 325°E, ‐1.9 km) has alluvial fans, flood deposits, possible lake beds, and clay‐rich sediment.

MSL Biosignature/Carbon compound Preservation Working GroupPreservation Working Group

The charge of this Working Group is to assess the potentialThe charge of this Working Group is to assess the potential diversity of biosignature/organic compound preservation windows that may be recorded in the ancient terrains that MSL will be exploring.  

This group is considering the range of possibilities in a general g p g g p gsense and also the specific opportunities identified at the candidate landing sites, as well as instrument capabilities and detection limits The group was provided a set of detaileddetection limits.  The group was provided a set of detailed questions to address.  

A report will be generated and put on the MEPAG web site.
